Method for adjusting balance of lift car

The invention discloses a method for adjusting the balance of a lift car, which comprises the following steps of: calculating the weight W (compensation) of the position of a compensation device at the middle layer of the lift car, stopping the lift car at the bottom layer position, and placing a balance weight W (flat) at the position of the corresponding compensation device of the lift car to simulate the weight W (compensation) of the position of the compensation device at the middle layer; the lift car is adjusted to be in a balanced state; when the lift car is located on the middle layer, the stress balance F guide of the lift car guide shoe is equal to 0; when the lift car is located on the bottom layer, the stress F < guide > of the lift car guide shoe is smaller than-F < permit >; when the lift car is located on the top layer, the stress F < guide > of the lift car guide shoe is smaller than + F < permit >; when the lift car runs in the whole building hoistway, the stress interval F < guide > of the l
